Bump version to SFRAME_VERSION_3. Introduce a new definition of SFrame
FDE for version 3, which is a duplicate of SFrame FDE in V2, for now.
In other words, no changes to the format specification yet.
GNU as emits SFrame V3 by default. SFrame encoder (ld) emits SFrame V3
sections. In a later commit, we will add a new command line option to
gas: --gsframe-3 which will bind the implementation in gas to emit
SFrame V3.
Also, adjust the testcases for the new version string
"SFRAME_VERSION_3".
